    Community Observatory image
    View Stars, Planets, Galaxies, Nebulae and even our own Sun through our telescopes. We have a 17" CDK Reflecting Telescope and a 4" APO Refracting telescope in the observatory for you to look through. While waiting your turn at the eyepiece you can view images on a monitor from our 14" SCT telescope outfitted with a special astronomy video camera that is many times more sensitive to light than your eyes. This allows you to see the beautiful colors of stellar nurseries, galaxies and more. We also have a 16" and 6" Dobsonian portable telescopes for you to use and learn about how to use a telescope. We also have an outdoor "Sky Theater" where docents give tours of the constellations outlining them with their laser pointers showing you what is up in the sky during your visit. On the first Saturday of each month we are open from 10am until noon showing you our Sun through our safe solar telescopes. We can show you the sunspots on the photosphere in "white light" and prominences, filaments, and flares in the chromasphere in Hydrogen Alpha light. Look for us on Facebook and YouTube. See more..
